3D look picture in rear projection tv is due to failure of convergence output ICs that will be replaced to fix this problem.

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

What you describe is probably a color convergence collapse, usually caused by a power amplifier failure, refer to the following link: http://www.youtube.com/watch?v=esk4nYZKFcg if this video is close to what you see on your TV you will need to replace both power convergence IC, the model KP57WS510(model given in your post) calls for STK392-510 both are available through UED, email [email protected], the above link gives an idea on what is needed for the IC replacement, that is if you're thinking of repairing the problem yourself.

Please try to access my link for the SM Power supply and understand if you can check out the power supply of your TV.

Common Symptoms include....
•Screen looks 3D
•Colors don't line up
•One or more colors can't be adjusted when using the convergence menu.
•Screen is bowed or warped.
•TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some photos of convergence problems

it looks like this but should have stk-392-560 number on it.

Two possible reasons here:

1) Does it look the same when you play a DVD etc or is it just with the sat receiver? If the same either way signal is not the problem.

2) On the set, turn the color all the way off and go if you can find one to a channel that is in black and white---What color is the screen? It should be something like a black and white picture.

The model indicated has a long history of problems with the three picture tubes.

If the picture is not black and white etc there is a manual way (not with the remote) to try to adjust for this---depending on your answer to the above I can tell you exactly how to do this---takes about 10 minutes and a Philips screwdriver---you do not have to be a tech to do it.

If I have told you something you did not know, rate this solution as very helpful as I do this here for free.

Hi Kelso73,
These red wires can be remove by opening the front speaker grill. One of the wires is connected to the focus control and the other one is connected to the high voltage module.
Let me know if you need further assistance.

Also check the micro fuses in this circuit to insure proper operation after replacing the IC"s

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

Hi,
Let me ask two questions,
1- Is it Sony KP-57WS510 model or any other one?
2- Does standby red light blinks 6 times for sure?
Because it is an error code that shows problem section and my answer/ solution would be based on above asked two question.
Thanks.

Your globe has gone in your tv you need to replace it then reset the lamp timer via he remote
